CUSTOMIZED TOTAL SOLUTION

  • Client Name : XXX SEMICONDUCTOR CO., LTD.
  • Client Requirement : Replacing 500 units from AC to DC type for saving energy and reducing electricity cost
  • Our Solution : After installation , we tested and compared the result of DC type AC type to prove energy saving effect to client.
  • Each unit can save NTD2,263 per year (about USD76 per year) (included heat load) ; 273kg-CO2/year
    500 units can save NTD1,131,500 per year (about USD37,72 per year) (included heat load) ; 136,500 kg-CO2/year
  • Client Name : XX Machinery CO., LTD.
  • Client Requirement : Client asked to install PAO testing pipe on AC and DC FFU
  • Our Solution : After discussing , we provided the drawing of installed positions to client and process the production.
  • Client Name : XX Technology Co., Ltd.            
  • Client Requirement : Client's AC FFU were damaged as EBM motor were unable to operate.
    Client would like to keep original casing and change damaged AC motor to DC type for saving cost.
  • Our Solution : We redesigned institution for DC motor and controller to fit in original casing.
    Now the client can systematic manage and maintain FFU.
  • Client Name : XXXXX OPTICAL CO.,LTD.
  • Requirement : The client required FFU control system compatible with their energy saving control system.
  • Solution : Supply communication interface RS485 and MODBUS RTU to connect to client's control system and set the stepless control system.
  • Client Name : THEXXXX  AIRTECH., JSC
  • Requirement :  The client required DC FFU 2'X4' have to meet the capacity 60CMM and change to wall mounting type.
  • Solution : Designing the high capacity FFU and lock air filter together with FFU to match requirement.

ULPA filter is an acronym for "Ultra Low Particulate Air filter" An ULPA filter can remove from the air at least 99.999% of dust, pollen, mold, bacteria and any airborne particles with a minimum particle penetration size of 100 nanometres (0.1 µm). An ULPA filter can remove (to a large extent, not 100%) – oil smoke, tobacco smoke, rosin smoke, smog, insecticide dust. The filter media is like an enormous web of randomly arranged fibres. When air passes through this dense web, the solid particles get attached to the fibres and thus eliminated from the air.

Porosity is one of the key considerations of these fibres. Lower porosity, while decreasing the speed of filtration, increases the quality of filtered air. This parameter is measured in pores per linear inch.

High-efficiency particulate air (HEPA), also known as high-efficiency particulate absorbing and high-efficiency particulate arrestance, is an efficiency standard of air filter.

HEPA filters meeting the standard must satisfy certain levels of efficiency. Common standards require that a HEPA filter must remove—from the air that passes through—at least 99.95% (European Standard) or 99.97% (ASME, U.S. DOE) of particles whose diameter is equal to 0.3 μm; with the filtration efficiency increasing for particle diameters both less than and greater than 0.3 μm.

HEPA was commercialized in the 1950s ULPA Filter, and the original term became a registered trademark and later a generic term for highly efficient filters. HEPA filters are used in applications that require contamination control, such as the manufacturing of disk drives, medical devices, semiconductors, nuclear, food and pharmaceutical products, as well as in hospitals,[9] homes and vehicles.
